Kylie and Kendall Jenner have both pioneered a few pretty out there trends over the years, but their latest is going to take things to a whole new level.
Why? 'Cos it involves hacking a big old hole in the front of your t-shirt and exposing your bra, duh.
VERY Regina George, we're sure you'll agree.
It started with Kendall rocking this one out and about this week, when she was photographed out in LA wearing a band tee with a hole lopped open to show her black bralette underneath.
But now lil' sis Kylie is also giving it a go and snapped a couple of herself also in a band t-shirt than had been cut right down the front to show off her opaque black bra.
Not quite sure we're ready to try this one - just THINK of the weird tan lines - but whadda ya reckon? Big trend or totes tragic?
